Various types of adhesive application devices for applying an adhesive to a base material are provided, for example, Japanese Utility Model Publication No. Sho 63-33659.
There is one as shown in Japanese Patent Publication.

This one is equipped with a rotatable roller which is rotatable so as to be orthogonal to the direction in which the base material is conveyed, and a part of the outer peripheral surface of the rotatable roller is in contact with the adhesive agent accumulating portion in which the adhesive agent is accumulated. The rotating roller rolls on the outer surface of the substrate that is being conveyed, so that the adhesive in the adhesive reservoir is continuously applied to the outer surface of the substrate by the rotating roller. ing. And in this thing, the application width of the adhesive agent applied to a base material may be adjusted according to the width dimension etc. of the conveyed base material. In this case, a plurality of adjusting plates that are in contact with the outer peripheral surface of the rotating roller are arranged below the adhesive reservoir so as to be adjacent to each other along the axial direction of the rotating roller. Adhesion applied to the outer surface of the base material by adjusting the contact width of the adhesive in the adhesive reservoir that contacts the rotating roller by advancing and retracting so that it is in contact with the rotating roller or away from the outer peripheral surface of the rotating roller. The coating width of the agent can be adjusted.

[0004]

However, in the conventional example as described above, the adjustment of the coating width is carried out stepwise by the forward / backward movement of the plurality of adjusting plates, that is, the adjustment of the coating width. There is a problem in that the adjustment can be performed only with the width of each adjusting plate that moves forward and backward, and the adjustment is performed stepwise, and the application width of the adhesive cannot be adjusted steplessly.

The present invention is intended to solve the above problems, and an object of the present invention is to provide an adhesive coating device capable of continuously adjusting the coating width of the adhesive.
